I am new in Forex and curious to know what leverage should be good for a newbie to use and also is it true that high leverage high risk? Plz, give your suggestions.
yes its true higher leverage = higher risk, its common sense. Only use what its in your margin account and keep hard stop losses until you get your methodology down.
First do not blindly assume high leverage is dangerous. You need high leverage to earn tons and tons and tons of money with a small amount of money. And that is the bottom line; to earn tons and tons of money. OK. Now to your question. It depends on the individual. For some people ( who have poor money management) , the lower the better. And for some other people ( who have good money management and will never ever over trade), the higher the better. So get to know yourself. We wouldn't be able to give you the appropriate answer.
As a newbie you should use a bet size of 0.000001 % per trade or better yet trade with simulator money.
1:50 is fine for Forex, any lower and your just wasting your time, I trade 1:200 Demo first, find a plan, try it live, fail back on demo, repeat for 10years.
If you're in Europe and subject to ESMA regulations then max retail leverage will be 1:30 on major pairs, less on minor pairs and indices.
Shouldn't you be trading without leverage as a beginner? Right now, your aim shouldn't be to make lots of profits but to hone your skills and preserve your account.
